Hi, I extracted some meta data by using exiftool from https://exiftool.org/
The command is exiftool -ee -G3 -v3 -api largefilesupport -m GS010450.LRV > tmp.txt
I get something like camera intrinsic (lens parameters) like below:
GoPro_KLNS = 1081.48076648172 -71.1130226589547 14.9704062180038 -8.043569224[snip]

the extracted parameters of front lens are 1081.48076648172 -71.1130226589547 14.9704062180038 -8.043569224 1.0999
also there are some other parameters like
GoPro_CTRX = 4.34998054662002
GoPro_CTRY = -1.8389908280984
GoPro_MFOV = 100
GoPro_SFTR = 1.00002960635123
and the transfrom between two lens
GoPro_SHFX = 23.1812458157391
GoPro_SHFY = 0.372738888409655
GoPro_SHFZ = 37.0191859120706
GoPro_ANGX = -0.0448620308967071
GoPro_ANGY = 179.946722520132
GoPro_ANGZ = -0.785323833803514
GoPro_CALW = 4056
GoPro_CALH = 3040
it seems that GoPro_ANGX GoPro_ANGY GoPro_ANGZ are rotation parameters between two lens, but I cannot guess the meaning of other number
Do you know the meaning of these numbers? I need them to transfrom the dual fisheye video from .lrv file to equirectangular video. Or you can teach me how to realize this in an other way?
